Do you have cleaner shrimp?

Too funny. Yes I do and I just googled shrimp spawning and it does look exactly like that. No wonder my fish were acting like they had too much sugar.

Such a small creature made such a big mess! Lol

Bingo.

Any yes, your fish will go bananas for the baby shrimp!

Keep track from now on. You'll start to see the egg sacs on the underside if the shrimp fairly regularly. And, if I remember correctly, they'll spawn every 2 weeks or so.

do you have a carpet anemone? mine spawn once a year and make the tank look like a very foggy day.

I do have a happy and fat carpet nem too. But the things looked kind of like bugs so most likely not a nem.
